A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Xigduo extended release tablets contain a combination of dapagliflozin and metformin. Dapagliflozin and metformin are oral diabetes medicines that help control blood sugar levels. Dapagliflozin works by helping the kidneys get rid of glucose from your bloodstream. Metformin lowers glucose production in the liver and also causes your intestines to absorb less glucose. Xigduo is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus. Xigduo is not for treating type 1 diabetes. Xigduo is also used to lower the risk of needing to be in the hospital for heart failure in adults with type 2 diabetes who also have heart disease. Xigduo is also used to reduce the risk of worsening kidney disease and death due to heart problems, and the need to be in the hospital for heart failure in adults with type 2 diabetes who also have chronic kidney disease.
Take Xigduo extended release tablets exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Your doctor may perform kidney function tests before you start taking Xigduo. Take with food to prevent an upset stomach. Swallow the tablet whole. Do not crush, chew, or break the extended-release tablet. You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda). Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency. Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination. Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule. Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual.
